For all their energy savings and process control benefits, variable frequency drive (VFD) systems have a downside too. When these drives fail, they can bring motor-driven industrial processes to a dead stop. To avoid this costly downtime, smart engineers carefully evaluate reliability when configuring a drive system. Fortunately, it is possible to avoid VFD-related cable failures and the associated downtime by paying attention to a few cable construction details. The overall performance of the drive system will also improve in many cases.
